Embodiment
See also Fig. 2 A, it is the schematic diagram according to a kind of radiating module of preferred embodiment of the present invention.Radiating module 2 of the present invention comprises a fan 20 and a radiator 30, and fan 20 is arranged in the radiator 30, and fan 20 is a Frame-free fan preferably, and can be an axial-flow type or a centrifugal fan, with Ben Tu, is example with the tube-axial fan.
Please consult Fig. 2 B and Fig. 3 simultaneously, Fig. 2 B is the fan of Fig. 2 A and the decomposing schematic representation of radiator, and Fig. 3 is the motor base of fan among Fig. 2 B and the schematic diagram of fastener.Fan comprises a motor base 21, an impeller 22, a motor (figure does not show) and at least one fastener 23.Impeller 22 all is arranged on the motor base 21 with motor, and motor is in order to drives impeller 22 rotations, and fastener 23 then radially extends from motor base 21.In the present embodiment, fan 20 has three fasteners 23, and these a little fasteners 23 are center and distribute the number number of right fastener of the present invention radially with motor base 21, can decide according to the attribute of actual product, in number and non-limiting the present invention of this fastener.
Each fastener 23 extends from motor base 21 horizontal radials and has axially extended upward a projection 25 again after being two buttress 24, and has an opening 26 between two buttress 24, an air communication mistake that can produce for impeller 22.After fan 20 and radiator 30 windings, because fan 20 itself does not have framework, and the design of opening 26 is arranged again between per two buttress 24, so air-flow can reach flowing of area on a large scale, make the radiator 30 of fan 20 belows all can be subjected to impeller 22 and rotate brushing of the air-flow that produces, so can reach good thermal convection, and then reach excellent radiating effect.
Then, please consult Fig. 2 B, Fig. 4 A and Fig. 4 B simultaneously, Fig. 4 A is the end view of the radiator of Fig. 2 B, and Fig. 4 B then is another visual angle schematic diagram of radiator.Radiator 30 comprises a plurality of first fins 31, a plurality of second fin 32 and a heating column 33, heating column 33 can directly contact (shown in Fig. 4 A) with a thermal source that is positioned at radiator 30 belows, in order to disperse the heat that this thermal source produces, this thermal source for example is a central processing unit, transistor, server, high-order drafting card, hard disk, power supply unit, running control system, electronic multimedia mechanism, radio communication base station or high-order game machine etc.
Those first fins 31 and second fin 32 all are located on the periphery of heating column 33, and those second fins 32 are positioned at those first fin, 31 belows.That is those first fins 31 are located on the first half of heating column 33 peripheries, and those second fins 32 then are located on the latter half of heating column 33 peripheries.After fan 20 and radiator 30 windings, fan 20 is arranged in those first fin, 31 formed accommodation spaces 311, and 21 of motor bases be positioned at heating column 33 directly over, shown in Fig. 2 B.
Now details are as follows with the winding process of fan and radiator, please refer to Fig. 2 B and Fig. 2 C, and Fig. 2 C is the part sectioned view of the fan of Fig. 2 A when combining with radiator.Whenever this first fin 31 all has a breach 312, and the position of breach 312 is corresponding to the position of flange 27.Because a plurality of first fin, 31 rings are located at the periphery of heating column 33,, can embed for the flange 27 of fastener 23, so fan 20 does not need directive restriction with radiator 30 when winding so its each breach 312 is just formed an annular groove that communicates jointly.Embed simultaneously in the breach 312 of two-phase neighbour's first fin 31 at least at the flange 27 of this each fastener 23, make fan 20 and radiator 30 stablize affixed effect so can reach.
When if fan 20 needs replacement or dismounting, because of first fin 31 itself has elasticity nargin, thus only need and will have first fin, 31 application of forces of joining to pull slightly with fastener 23 toward the outside, just the flange 27 of fastener 23 can break away from the breach 312 of first fin 31.After the flange 27 for the treatment of all fasteners 23 all breaks away from the breach 312 of first fin 31, can be easily with fan 2 removals.Thus, the present invention not only removes from having now with the screw locking needs to use the shortcoming of hand tool, and does not need additional parts just can finish winding, saves the required time of manual work.Moreover, save material and cost of labor simultaneously, and it can load and unload the characteristics of replacement fast, more can completely show the excellent specific property of radiating module of the present invention.
Hold, referring again to Fig. 4 B, heating column 33 is that a material is a solid cylinder or the plume that a metal or a metal alloy are constituted.Plume has capillary structure, working fluid and a water injection pipe 331, and working fluid injects plume inside by water injection pipe 331.
Every adjacent two first fins 31 are snapping and be located on the periphery of heating column 33 each other, and every adjacent two second fins 32 are snapping and be located on the periphery of heating column 34 each other, and each first fin 31 is each second fin 32 of positive L type approximately and then is an inverted L shape approximately.
In sum, radiating module of the present invention and fan thereof, flange by fastener is corresponding chimeric with the breach of first fin, not only can limit fan and produce upper and lower displacement, reach the effect of location, and under the acting in conjunction of a plurality of fasteners, more can reach and combine closely, abate the noise, strengthen fixing effect.Adopt design of the present invention, not only can load and unload fan fast, must be so that the trouble of tool locking by hand when removing existing assembling from, and because of fan itself does not have framework, so air-flow can reach the mobile of area on a large scale, reach great heat radiation effect.
Yet the present invention is not limited thereto, and sees also Fig. 5, and it is connected with the schematic diagram of a rotating speed switching device shifter for the fan side of Fig. 2 B.Be that for ease of clearly demonstrating, the fan among Fig. 5 only shows the part of motor base 21 and fastener 23 what this need specify.Fan 2 more can comprise a rotating speed switching device shifter 51, and it is arranged on the fastener 23 and with motor and is electrically connected.One end of rotating speed switching device shifter 51 is a switch, is available for users to pull with finger control, and the other end of rotating speed switching device shifter 51 then is a terminal, can be connected to the circuit board (figure does not show) in the motor on the motor base 21.
Rotating speed switching device shifter 51 is changeable and impeller 22 is rotated with two or more at least different rotating speeds.That is when rotating speed switching device shifter 51 was not done switching, impeller 22 was rotated with a fixed rotating speed, for example is 2080r.p.m; Required according to the external world if heat increases, in the time of need dispelling the heat fast, then the user just can point the switch of pulling rotating speed switching device shifter 51 easily, impeller 22 is rotated with another fixed rotating speed, for example be 2900r.p.m, just can reach the purpose of dispelling the heat fast thus by bigger rotating speed is provided.
In addition, fan of the present invention can on its circuit board, be equipped with one can be luminous an indicator light or a LED lamp, and the impeller of fan made with a light-permeable material or a transparent/translucent material, as materials such as acryl, polyesters plastic cement, and motor base and fastener also can light-permeable material all of the same race for this reason or the transparent/translucent material make.Thus, when wheel rotation, the light that self-indication lamp or LED lamp are sent then can reach dazzling beautiful visual effects by the impeller that constantly rotates, and wherein light can be a white light or coloured light.Moreover the number of indicator light of being installed on the circuit board or LED lamp does not limit, and also can adopt indicator light or the LED lamp that sends different color light more than 2 kinds simultaneously, more can reach the special image effect behind the mixed light.
The above only is an illustrative, but not is restricted person.Anyly do not break away from spirit of the present invention and category, and, all should comprise in the appended claims its equivalent modifications of carrying out or change.
